Safely Removing Local Docker Images Without Affecting Remote Repositories

You want to remove all local images that belong to username/reponame regardless of their tag, but DO NOT delete anything from Docker Hub (remote). Only clean local.

Here is the safest way:

docker images "username/reponame" --format "{{.Repository}}:{{.Tag}}" | xargs -r docker rmi

✅ Explanation:

• It will only delete local images of username/reponame:*

• Remote images on Docker Hub are untouched

• Safe to run multiple times (won't fail if already deleted)

 You just want to remove only the <none> tagged images from username/reponame.

Here is the exact command for your case:

docker images "username/reponame" --filter "dangling=true" --format "{{.ID}}" | xargs -r docker rmi

✅ Explanation:

• --filter "dangling=true" targets images with <none> as tag

• --format "{{.ID}}" gets only their Image ID

• xargs -r docker rmi safely removes them if any exist

• Safe to run multiple times
